Patent EP-0322859-A2 (EP)
Inventor: MAKINO SHINICHI
IPC: H01L21/00
Filed: 1988-12-27
Abstract: A pair of solder coating rolls are disposed hori­zontally adjacent one another for rotation about parallel horizontal axes, and are spaced apart to define a narrow vertically-oriented nip therebetween for accommodating a lead frame therein. Lower parts of the rolls contact a solder bath, and counter rotation of the rolls carries the solder upwardly on the periphery of the rolls to create a small pool of solder at the upper end of the nip. The lead frame is driven vertically upwardly through the nip, which nip has a minimal dimension greater than the lead frame thickness. The lead frame is driven vertically upwardly at a linear speed which is different from, and preferably slower than, the peripheral speed of the solder coating rolls. This enables preheating of the surface of the lead frame due to its longer exposure to and contact with the hot solder which coats the periphery of the rolls, thereby improving the wetability of the lead frame surface. At the same time, this upward movement of the lead frame through the nip and through the pool of liquid solder permits a solder coating of high quality and uniformity to be applied to the lead frame.

Abstract: A phase comparator generates a reference pulse signal equal in duration to one bit cell, and a variable pulse having a duration representative of the duration and time displacement of the leading edge of a data pulse from the centre of the bit cell. The phase comparator includes the two D-type flip-flops (Q1,Q2) arranged so that the variable pulse is initiated by the leading edge of the data pulse in the one bit cell, the reference pulse is initiated by the edge of the clock pulse at the end of the one bit cell, and both pulses are terminated by the edge of the clock pulse at the end of the next bit cell. Hence, only clock edges at the bounds of the bit cell affect the pulse durations and the comparator is insensitive to clock asymmetry. A charge pump associated with the phase comparator provides a pump down signal amplitude equal to 3/2 the pump up signal amplitude to correct the relationship that the variable pulse (which generates the pump up signal) is 3/2 the duration of the reference pulse (which generates the pump down signal) where the data pulse edge is nominally in the centre of the bit cell.

Abstract: The switch includes three pairs of CMOS-FET transistors (11,12; 21,22; 31,32) having their channels serially connected between two switch terminals (14,18). The second pair (21,22) of CMOS-FETs controls the first pair (11,12) in either a latched-on or latched-off state. The control of the said second pair of CMOS-FETs, in turn, is by the third pair (31,32) of CMOS-FETS. The gate electrode of the first transistor (32) of the third CMOS-FET pair serves as a turn-on terminal (37) for changing the conduction states in the second pair (21,22) so as to latch the first pair (11,12) into a state of current conduction between the two switch terminals (14,18). The gate electrode of the second transistor (31) of the third pair serves as a turn-off terminal (34) for changing the conduction states of the second pair (21,22) so as to latch-off conduction between the two switch terminals.

Abstract: The present invention relates to styling agents comprising adhesive copolymers along with a volatile diluent useful in products such as shampoos and conditioners which provide hair styling hold. The monomer components in these copolymers are randomly distributed in the copolymer chain, preferably to form a substantially linear chain. Preferably, at least one of the monomer components is selected from vinyl pyridine, acrylate amides and methacrylate amides and one of the other monomer components is selected from butadiene, isoprene, isobutene, acrylate esters, methacrylate esters, vinyl alkyl ethers, alkyl-­substituted butadienes, and chloroprene. These copolymers also have a single glass transition temperature within the temperature range of from about 0°C to about 150°C. The volatile diluents useful in these styling agents can be hydrocarbons, esters, ethers, amines, alkyl alcohols, or volatile silicon derivatives.

Abstract: In the screen-printing process, a flat article to be printed, for example a printing material, is laid onto a printing table and, if appropriate, held there by means of a vacuum, and then a stencil having on its rear side the ink to be printed on is lowered with the screen and its front side onto the article and the ink at the same time pressed through the screen onto the article by means of a doctor moved over the rear side of the stencil. The stencil is subsequently lifted off, and the printed article comes free from the printing table. An ionising electrode operated by direct voltage is moved parallel to the doctor.

Abstract: In a serial input-output circuit comprising a memory device (15) for memorizing an input serial bit sequence as memorized bit groups, each consisting of a predetermined number of parallel bits, first and second bidirectional shift registers (21, 22) are serially connected through a ring connection (24, 25). A storing arrangement (35-37) is connected to the respective shift registers and directly to the memory device for bit parallel storage of the parallel bits of a selected one of the memorized bit groups in a selected one of the shift registers. An output serial bit sequence is produced from one of the shift registers selectively forwardly and backwardly as regards time relative to the input serial bit sequence. The storing arrangement may comprise a register selector (35) and first and second bit parallel connections (36, 37). The register selector selects the selected shift register and bit parallel loads the selected shift register with the parallel bits of the selected bit group through one of the bit parallel connections that is connected to the selected shift register.

Abstract: An actuator for an objective lens (34) in an optical head which provides a compact structure that does not move the laser beam (29) relative to the objective lens in the tracking mode. The low profile optical head design is accomplished by designing the optical beam path in the same space occupied by the tracking and focusing motor (20, 22, 24, 36, 38, 42, 46, 52; 10, 12, 14, 16, 18, 26, 40). A mirror (48) reflects a laser beam (29) from a laser (28) at an angle to an objective lens (34). The objective lens (34) and the mirror (48) are coupled together in a manner allowing movement of the objective lens (34) relative to the mirror (48) along the path of a laser beam (29) from the mirror (48) to the objective lens (34). The objective lens (34), mirror (48) and the coupling mechanism are all moved along the path of the laser beam (29) between laser (28) and the mirror (48) for tracking control. Because the mirror (48) moves with the objective lens (34), there is no beam clipping or beam distortion. For focusing, the objective lens (34) is moved relative to the mirror (48). The laser (28), the detector (58) and their associated optics are stationary, with only the mirror (48) and objective lens (34) being moved, thus limiting the mass moved and the power requirements. The simple structure eliminates the need for a fiber optic cable.
